Both methods utilize the same principle, only one is direct about it and the other more ponderous while reaching the same end.
Take a bike you don't mind dropping and push it forward from the rear (no hands on the bars), then lean it gently to the left (weight-shift) and watch closely as the front wheel initially steers right, inviting the CG to fall further left, before following the lean into a like path through the turn.
For a bike to lean the contact patch must be driven out from underneath it. Whether this happens by intent (active counter-steering) or comes by surprise (belief in weight-shift being "another" way) is no matter. The same cause-effect relationship exists.
For convenience let's just call these methods conscious and unconscious counter-steering.
If I want to dodge a dead skunk I will opt for 'intent'.
